Abstract: Изобретение относится к сварке и может быть использовано при автоматической сварке тонкостенных заготовок неплавящимся электродом. Присадочную проволоку подают в зону сварки по кривой в плоскости, перпендикулярной к поверхности свариваемой заготовки до получения на вылете заданного радиуса кривизны за счет остаточной деформации и снятия в проволоке внутреннего напряжения. Проволоку подают с ее касанием поверхности свариваемой заготовки в точке пересечения с осью сварочной горелки. Радиус кривизны проволоки на вылете в зону сварки формируют путем деформации проволоки. Криволинейный тракт устройства для подачи проволоки выполнен с двойной кривизной. Конец тракта с большей кривизной закреплен в кронштейне, а с меньшей - в державке. Мундштук присоединен к тракту посредством переходной втулки. Выходное отверстие мундштука выполнено плавно расширяющимся в направлении свариваемой поверхности заготовки. На свободном торце мундштука вдоль линии эксцентриситета выполнен скос под углом 45 o  до верхней границы выходного отверстия. Расстояние от козырька мундштука до оси сварочной горелки составляет 15...20 мм.
